Alright, as many of you know the northeast and everywhere has been FREAKIN COLD, my truck has basically NO heat at all. It takes about and hour and half for it to make the heat actually come out of the heater. I was talking about it with my dad and he said i might have a 180 thermostate, so if i got a new one it would help it out a lot. Could this be true? or is my heater itself just dead?
